The A&C Bus Corporation, also known as the Montgomery & Westside Bus Owners Association, is a bus company in Jersey City, New Jersey. All buses operated by A&C are known for their solid red line on the side of the bus and the phrase "use the bus card on this bus" on the front of the bus.

Like many other private bus lines in the state, its fleet is made up of buses leased from New Jersey Transit.

Prior to A&C Bus Corporation's operation of the Bergen Avenue route, the route was operated by Bergen Avenue IBOA. When Bergen Avenue IBOA was unable to make an insurance payment, it abruptly stopped running its only route on March 12, 2011, the New Jersey Department of Transportation (NJDOT) granted emergency operating authority to A&C Bus Corporation. A&C Bus Corporation began operating the route on March 16, 2011 with no changes in bus fares, however it reduced operating hours to 6:30AM–10:00PM (running every half hour). Since that time, the owners of Bergen Avenue IBOA stated that it intended on selling the rights to operate the route, however the NJDOT stated the company's rights ceased when it abruptly stopped operating with no warning to passengers.[3]
